Computer Memory Measurement Units

Computers and storage mechanisms (CD-ROMs, hard drives, USB flash drives, DVD-ROMs, Blu-ray Discs, etc.) need to hold much larger values than what a byte can hold (0-255). Thus, the terms kilobyte, megabyte, gigabyte, terabyte, petabyte, exabyte, zettabyte, and yottabyte were created to represent such large amounts of information.
